# Thundurus (Japanese) #042 — EX Battle Boost

## Summary

Japan got Thundurus in EX Battle Boost in July 2013, nearly four months before the English version arrived in Legendary Treasures, which makes this Japanese edition a genuine early look at the card. The illustration puts the storm Genie, pale blue with a white mane and dark spiked rings, over a cloud with craggy purple mountains behind it. Fans still prize Thundurus as one of the Forces of Nature. The modelled guide sits at $3.63 with no copies traded in 30 days; no PSA population is on file, and a PSA 10 would fetch about $250 against $65 in grading fees.
